Equivalently, one can view an extra sum of squares as measuring the marginal increase in the regression sum of squares when one or several predictor variables are added to the regression model. Example: Body fat (Y) to be explained by possibly three predictors and their combinations: Triceps skinfold thickness (X1), thigh circumference (X2) and ...

Infer answers to the questions of interest. The assumptions of the simple linear regression model appear to, by and large, hold and there are no influential points. The question of interest is to predict Pcalls based on daily low temperature and give a prediction interval that is likely to contain the Pcalls for a given day with a daily low ...

In multiple regression the marginal relationships between the response (Y) and the individual predictors (X) convey little useful information about their role in a multiple regression model! Diagnostic plots (residuals vs. fitted and residual normal quantile) for the final three-predictor model are shown below.

Multiple Regression Models and Significance Tests. Many practical questions involve the relationship between a dependent or criterion variable of interest (call it Y) and a set of k independent variables or potential predictor variables (call them X1, X2, X3,..., Xk), …

The goal of this lab is to illustrate basic multiple regression. The simplest multiple regression is a 2 predictor multiple regression problem. Let’s work through an example of this situation. We will run a couple of multiple regression models and orient ourselves to the relevant output and correct interpretations of the parameters.
